Periodically poled aluminum scandium nitride bulk acoustic wave resonators and filters for communications in the 6G era
{{output}}
Bulk Acoustic Wave (BAW) filters find applications in radio frequency (RF) communication systems for Wi-Fi, 3G, 4G, and 5G networks. In the beyond-5G (potential 6G) era, high-frequency bands (>8 GHz) are expected to require resonators with high-quality factor ... ...
